I've been running adapters for almost 10 years. No issues.

I think results vary and depend almost completely on:

Offset / Backspacing
Hub-Centric / Not
Driving Style

I like deep dish wheels, that have a smaller backspacing. Typically called a RWD offset wheel. This moves the weight distribution towards the center of the rim instead of the outer edge as seen on many FWD offset wheels. Newer cars, even RWD, tend to have the larger backspacing. Maybe the larger the backspacing, the more likely bearing wear will be.

There are two different kinds of adapters. Hub-centric are machined to fit spot on over the lip on the outer edge of the hub. This perfectly centers the adapter and puts the bulk of the weight on the hub itself instead of the studs...which are further from center on the hub. That too could contribute to bearing wear.

Finally, driving style. I'm a cruiser. I like torque, medium speeds, and mildly curvy to straight roads. I'm easier on my suspension and bearings because I am not an aggressive twisty high speed autocross driver. I think the more aggressive a driver is in turns, affects the wear of the bearings, and in turn, other suspension components.

Moot point. For every five folks who post and say not to use them, five more will post and say they're fine.

No debate if you run stock wheels.

I run stock wheels.

:buhbye:

As far as after market wheels, yeah, run the risk if you want the wheels.

However, there are a lot of folks who have or want to install late model Corvette rims on a C3. These guys have to use adapters...no debate.

So...it's 'kind' of like stock wheels, since they are stock...just not a stock application. LOL.
